Delivering liquid compositions to an interior site in the body. More particularly, the invention provides devices, systems, and methods for facilitating percutaneous access to an implanted port for performing peritoneal dialysis in a sterile condition. In one aspect the invention provides an apparatus for use in peritoneal dialysis comprising a first container (30), and a second container (50) wherein at least one of the containers is filled with unused dialysis fluid. The first and second containers (30, 50) are fluidly coupled by a first tube (31), and a second tube (51) to a junction (40). A single common tube (60) fluidly coupled to the junction provides a fluid pathway to a percutaneous access member (20) connected to the end of the single common tube (60). The access member (20) has a minimun bore diameter of 1.16 mm capable of providing high volumetric flow rates.

L'invention concerne en général l'administration de compositions liquides à un site intérieur dans le corps. Elle concerne en particulier des dispositifs, systèmes et procédés pour faciliter l'accès, par voie percutanée, à une chambre implantable pour effectuer une dialyse péritonéale dans des conditions stériles. Un aspect de l'invention a pour objet un appareil utilisé pour une dialyse péritonéale, comprenant un premier contenant (30) et un deuxième contenant (50), au moins un des deux étant rempli de fluide de dialyse non utilisé. Le premier et le deuxième contenants (30, 50) sont placés en communication fluidique avec une jonction, respectivement par un premier tube (31) et un second tube (51). Un tube (60) commun unique placé en communication fluidique avec la jonction (40) assure un passage fluidique vers un élément d'accès (20) percutané, relié à l'extrémité du tube (60) commun unique. L'élément d'accès (20) présente un diamètre de trou minimal, de 1,16 mm, permettant d'obtenir des débits volumétriques élevés.
